CASTRO VALLEY — An apartment fire claimed the life of a cat Saturday morning, but firefighters and paramedics were able to save three others — including two that had to be resuscitated — according to an Alameda County Fire Department spokeswoman.

Firefighters rushed to the one-alarm fire at 20293 Anita Ave. at 8:17 a.m. Saturday, spokeswoman Aisha Knowles said. While searching to confirm that no humans were inside, they found four cats and rushed them to safety.

One cat died, two were saved using a pet resuscitation mask, and one fortunate feline required no medical attention, Knowles said.

The fire, which began in the apartment’s kitchen, was confined to that apartment and knocked down in less than 10 minutes. The cause remains under investigation.

Otto Warmbier was arrested in January 2016 at the end of a brief tourist visit to North Korea. He had been medically evacuated and was being treated at the University of Cincinnati Medical Center when he died at age 22.
